A computer is a programmable machine. The two principal characteristics of a computer are: it responds to a specific set of instructions in a very good manner and it can perform a pre-recorded some list of instructions or programs. From those basic characteristics, the computer has grown up to five generations and its functions have extended. The first computer was invented in 1940 with a tube form and had many deficiencies. The use of a great deal of electricity, big storage and generation of a lot of heat often caused malfunctions. It was firstly used by the U.S Census Bureau. Hence, in 1956 the scientists created the second generation of computer with a transistor form. It was smaller and more efficient in energy usage. But still, the transistor generated a great deal of heat that subjected the computer to damage. The second computer generation was developer for atomic industry at that time. As the growth of second computer generation, in 1964 the third was developed into smaller and placed on a silicon chip, called semiconductor. This newer generation, allowed users to have interaction through monitor and keyboard. And because of that, the computers now were accessible for mass users. Then in 1971, the fourth generation was developed with thousands of integrated circuits were built onto a single silicon chip as microprocessor. Developed by IBM in 1981 and Apple in 1984, the microprocessors began to be used by the realm of desktop computers and into many areas of life as more and more everyday products. The fifth generation of computer actually is still in development. The goal of fifth computer generation is to develop devices that respond to natural language input and are capable of learning and self-organization. However, there are some applications, such as voice recognition, that are being used today. The computer technology has had massive impact that has invaded all aspects of life,...
